Giving a bool any value other than 0 | Giving a bool any value other than 0 or "false" will set it to 1 or "true". For instance, assigning a float to a bool will make the bool "true" or "1" unless the float value is "0.0", which will become "false". On Macs, you can make reference to bools without any relational operator. The following statements are equivalent in Mac Oni: | ||
if (example) | |||
if (example eq true) | |||
However, Windows Oni will fail to evaluate bare references to bools, and testing indicates the possibility of other bugs existing in Windows Oni's handling of bools. Additionally, Bungie West uses virtually no bools in Oni's scripts. Since ints are handled much more reliably, it's recommended to use ints instead of bools, assigning them the values 1 and 0 to represent "true" and "false". | |||
